FINISH-REMOVER.

To all whom it may concern:

Be it known that I, CARLE'roN Ennis, a citizen of the United States, andresident of Larchmont, in the county of Westchester and State of NewYork, have made certain new and useful Inventions Relating toFinish-Removers, of which the following is a specification.

This invention relates to finish removers and relates especially tocompositions particularly adapted for the removal of fioor Waxes andsimilar finishes.

Volatile alkaline loosening material, such as ammonia, has an energeticsoftening and loosening action on most fioor waxes which containbeeswax, and for this reason finish removers comprising ammonia orsimilar loosening agents are particularly desirable for use in removingsuch finishes applied to floors and the like. Where'ammonia is used itmay be conveniently incorporated with' the other remover ingredients byallowing ammonia gas to percolate through the remover, preferably whenin a somewhat chilled condition in a deep tank or other vessel. Thisaction may be continued until the absorption of the ammonia by theremover has substantially ceased. In some cases small quantities ofstrong ammonia water may be added to the other remover ingredients aftertheir combination and in such cases a small proportion of oleic or otherfatty acid may be used or beeswax may, be employed in the remover toprevent any separation of the ingredients. Suitable penetrating finishsolvent material, that is, solvent material of a generally benzoliccharacter or action in removers may be used in such removers, such asbenzol, toluol, xylol, cumene, as well as the corresponding petroleumhydrocarbons, benzin, gasolene, and so forth. Carbon-bisulfid is also adesirable wax solvent and carbontetrachlorid and similar chlorinatedcompounds are useful since they reduce the infiammability of themixture. wax and other finishes, such as paints and varnishes, looseningfinish solvent material, that is, finish solvent material of a generallyalcoholic character or action in removers Specification of Letters.Patent.

are desirable, including the strict alcohols such as methyl ethyl,propyl,butyl, amyl and benzyl alcohols which are preferably used in'their commercial forms for the sake of cheapness, including denaturedalcohol and other solvents of a generally alcoholic character or action,such as acetone and other ketones, acetone oil, light tar oil, resinoil, and so forth, composite solvents being usually more desirable andhaving a better generally solvent action in removers.

Although not necessary in all cases it is usually desirable to employsuitable stiffening material in the remover, such as wood flour, starch,whiting, infusorial earth and soapy or waxy bodies, such as ceresin,parafiin, bayberry tallow, beeswax, ozocerite, oleic and other fattyacids, palm oil and nitrocellulose may also be used, many of which formefiective evaporation retarding films over the exposed surface of theremover when in use.

A typical illustrative type of remover of this character maycomprise'benzol 13 gallons, wood alcohol 12 gallons, beeswax 3 pounds,suitably combined in the usual way, preferably by agitation at slightincrease of temperature and then saturated with ammonia gas by allowingthe gas to percolate through the chilled remover in a suitable tank.Anotherillustrative composition may comprise benzol 15 gallons, acetone10 gallons, which may be used in the form of methylv acetone, ifdesired, paraffin wax 4 pounds, oleic acid 4 pound combined as indicatedand two quarts of 26 ammonia thoroughly incorporated therewith.

This invention has been described in connection with a number ofillustrative ingredients, formulas, proportions and processes, to thedetails of which disclosure the 15 gallons, loosening finish solventmaterial formed by incorporating penetrating and 10 gallons, oleaginousthickening material loosening finish solvent material, Waxy stilland 2quarts of ammonia Water of about ening material and ammonia.
